@neologist,
I think so, too, Neo.
By the way...about the "dragging" element.
I would hope everyone realizes that it is common courtesy to be as careful as possible not to unduly damage or dirty up the corpse while dragging it. Doing so would be at least as serious a breech of golf etiquette as talking or moving while someone else is putting.
But consideration of the “be careful while dragging the corpse” courtesy does not in any way excuse the foursome (now actually playing as a threesome) from keeping pace. Speed of play is always paramount. No ranger worth his salt will buy something like “we've gotta drag this dead guy” as an excuse for an open hole between groups.
